I laughed when goals 3 and 4 went in. It's hard to even be angry about it anymore, I just feel disconnected from it all emotionally.
Though I don't think the foul on Henderson was a foul. They both jumped for it, Henderson felt the contact and went over. Are you supposed to only let the keeper challenge for an aerial ball whilst you just stand there and let him? The foul on Dalot for one of their goals was a much clearer foul, but wasn't ruled out for whatever reason.
Palace deserved the win, probably should have had a couple more, and we deserved to be humiliated. But officiating makes this game hard to watch at the best of times.
